VALVE.

Application led February'21, 1922. Serial No. 538,273.

To all whom t lmay concern Be it known that I, THOMAS O. MOUNTAIN, acitizen of the United States, residing at El Paso, in the county of ElPaso and, State of Texas, have invented new and usefulImprovements inValves, of which the following is a specification.

The object of this invention is to provide means for preventing a tankor container from overflowing, when being filled through a hose or thelike.

Another object of the invention is to make.

such means automatic so that as soon as the liquid reaches a pointadjacent the top of ose or other Afilling medium will be stopped.

This invent-ion also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters 'denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is an elevation of the invention.

F igure-2 is a longitudinal sectional view thereof showing the partsthereof in inoperative position.`

Figure 3 is a similar view showing the parts in operative position.

lfigure 4 is a view showing the invention applied to a .gasolinedelivery pump.

Fi re 5' is a view showing the invention applied to another kind ofpump.

The remaining figures are detail views.

In these views 1 indicates a faucet which is adapted to be connectedwith a hose 2 or the like which delivers the liquid from the source ofsu ply to the passage -3 of the faucet. A va ve 5 controls the flow ofliquid through this passage, said valve being adapted to engage a seat6, which separates one part of the passage from another part, when thevalve is in closedposition and 4said valve is adapted to engage a recess7 `when in open position, said recess being below the level of thepassage sothat the valve will not interfere with the flow of liquid. Imay make the bottom of this recess removable, as shown at 8, so as tofacili tate assembling of the parts. A cylinder 9 liquid from thepassage into the cylinder. v

A piston 12 is located in the cylinder and this piston is secured to thevalve stem, as shown. The valve stem passes through a hole in the top ofthe cylinder and the lower end of the. cylinder is provided with anopening 13 which communicates with the atmosphere. A jacket 14 is formedaround the outlet portion of the faucet and the space formed Vby thisjacket is in communication with the cylinder through the port 15. Apassage 16 has one end connected with the upper end of the cylinder andits other end is adapted to be connected to a pipe or tube 17 whichleads toa suction creating part hereinafter referred to.

The drawings show the inventionY applied to gasoline delivering pumps ofthe two different types, though it will of course be understood that theinvention can be used in filling containers of all kinds. n

Referring to Figure 4 the outlet of the pump 18 is connected by the hose19 with my improved faucet so that the gasoline flowing from the pumpswill pass through the hose into the faucet and from the faucet into-thetank of the motor vehicle. The piston of the pumpg 18 is provided withthe usual rack 20 which is engaged by 4the toothed wheel 21 connectedwith the handle 22. A small cylinder 23 is supported by the -pump andthe lpiston 24 of the cylinder.l is connected with t e rack so that thepiston will move when the pump is being-actuated. The bottom ofthecylinder 23 is connected by the tube 17' with' the paage 16 so that asthe pump is actuated air will be drawn through the jacket space, intoIcylinder 9,' through passage 16 and tubing 17 f into the lower partuofthe cylinder 23. vAs the valve 5 is in open position the piston 12 willbe below the port 15 and will not interfere with A valve 5 upon its seatthus stopping the flow of liquid through the faucet. The resulting backpressure in the pump holes will prevent further movement of the pumpparts so that the operator will know that-the tank is full and thusprevent overflowing of the tank. The hose and faucet can be drained bypushing downwardly upon the valve stem, which projects above the top ofthe cylinder, so as to force the valve from its seat.

Figure 5 shows the device applied to a visible form of pump in which abottle is used to receive the liquid pumped out of the supply tank.After the proper amount of liquid has been pumped into the bottle avalve 26 is` opened to permit the liquid in the bottle to flow throughthe holes into the tank of the vehicle. ln this case l connect thetubing 17 with the top of the bottle so that the dow of liquid therefromwill create a suction in the cylinder and as soon as the How of air iscut off by the liquid reaching the -end of the jacket 'space thissuction will cause the piston in cylinder 9 to raise thus closing thevalve 5 and preventing the liquid from passing into the tank. Theoperator must .then close valve 26.

It will thus be seen that the device will work automatically to preventoverflowing of tanks or other containers. Any suitable form of suctionmeans may be connected with the cylinder for movin the valve to closedosition when the tan or container is fille i It is thought from theforegoingl description that the advantages and novel features inventionwill be readily apparent.

of may I esire it to be understood' that ll may make changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaims.

What l claim is l. A faucet of the class described comprising a normallyopened valve, a suction chamber connected with ther faucet and. throughwhich. the valve' stem passes, a piston in said chamber connected withthe stem, a connection from the chamber to a point adjacent the outletend of the faucet l:3nd means for drawing air from the charn- 2. Adevice Aof the class described comprising a' body having a passagetherethrough, means for connecting one end of said passage to a sourceof liquid supply, a valve for controlling said passage, a cylinderforming part of the body and through which the valve stem passes, apiston in the cylinder connected to the valve stem, a passage leadingfrom said cylinder to a point adjacent the outlet end of the passage andmeans for drawing air from the upper end. of the cylinder.

3. ln combination with a vgasoline pump, a faucet connected with thehose thereof, a normally opened valve in the faucet, a cylinder formingpart of the faucet and through which the valve stem passes, a piston inthe cylinder connected with the stem, a passage leading from the lowerpart of the cylinder to a point adjacent the outlet end of the faucetand means associated with thel pump for drawing air from the top of thecylinder.

ln testimon whereof I aflix 1n signature..
